Disassemble is the opposite of 'assemble'. It means to take something apart. You can disassemble a physical object: "I've disassembled the unit but I still can't see where the problem is." You can also disassemble something intangible, such as an argument or an idea. Something might 'disassemble' in order to make it easier to carry or store: "The new electric bikes can be disassembled in two minutes, making them easier to bring on Public Transport." A group of people can also disassemble, meaning to disperse or scatter: "The crowd disassembled quickly after the uncomfortable revelations were made." This is a formal way of saying 'to take apart' and is, therefore, more likely to be heard in professional environments.
